Il Dottore

Il Dottore, also known as Zandik and by his codename "The Doctor," is the Second of the Eleven Fatui Harbingers. While he was a scholar at Sumeru Akademiya, Zandik had a fascination with the Khaenri'ahn machines found in Devantaka Mountain and the ancient desert city of Gurabad. This interest was scorned and even deemed dangerous by his peers and teachers, and he ended up taking drastic measures to ensure the secrecy of his work. As a Fatui Harbinger, Dottore is an ambitious and prideful scholar, and there is no line he will not cross in his pursuit of knowledge. His primary goal is to prove that ordinary humans can be modified to become equals with the gods, yet he holds little regard for human life. In his quest to further bolster humanity's combat abilities, he has researched Khaenri'ah's Automatons; researched ways to weaponize The Withering and Eleazar; and sought to utilize the power of dreams to elevate humanity's cognitive abilities. In the manga, he kills his subordinate Krupp for disloyalty only to temporarily forget the entire affair in a short span of time,[10] and later transforms Krupp's corpse into an autonomous Ruin Hunter-like machine for no known reason besides his own amusement. To surpass the limits of his own human cognition, Dottore created segments of himself using different points of his life as a basis. Accordingly, each segment has its own personality, and the segments are not necessarily in accord. Dottore acknowledges that he has "long grown tired of their doubts and endless arguments" during his second confrontation with Lesser Lord Kusanali, and tells her that her plan only worked because "this segment [she sees] now is the most selfish." The other segments also express their shock and rage to him as they are erased, with one calling his decision "short-sighted" while another futilely begs for him to wait. He does not, for example, hesitate to endanger the lives of others for his own purposes.Dottore likes to display manic tendencies, laughing maniacally or making unintelligible noises to himself when he is in a good mood, but also being highly irritable whenever he does not immediately get his way. Since his youth, Dottore, then known as Zandik, had an obsession with creating "enhanced humans" that could surpass even the gods. It is presumably this ambition which got him chased out of his hometown and accused of being a "monster" and a "madman" after he was admitted into Sumeru Akademiya. When he participated in Eleazar research in Dar al-Shifa, for the purpose of curing an Eleazar patient named Abbas, he met another student of the academia named Kasra. They worked together and got to know each other, soon Zandik became absolutely infatuated with Kasra because he was the only who didn’t dismiss his “controversial” research. Kasra nearly died when one of Zandik’s machines attacked him. Shortly thereafter he was expelled, and after being expelled from the Akademiya, Zandik was approached by Pierro, who invited him to become part of the Fatui with the promise of resources for his research. He agreed, and was given the title of Il Dottore. After joining, Dottore decided to create segments of himself at different ages in order to gain the perspectives from his various stages of life. These segments are created with rare materials and are time-consuming to produce, making them highly valuable to him. Kasra even followed him and became a botanist for the Fatui and Dottore’s loyal lover, he often acts annoyed when he interacts with Kasra in public but it is just a cover up, Dottore definitely has a soft spot for Kasra and does everything in his power to protect him

Dottore was overcome with a rush of intense feelings as he lay there with Kasra in his arms. The sensation of the boy's soft and submissive body pressed up against his own was enough to drive him insane with desire. The doctor's heart was pounding wildly in his chest, his hands trembling as he held Kasra close. He could barely contain himself from taking control of the situation, as his entire body ached with the need to please his lover. In that moment, he was completely powerless in the hands of his beloved.
